Re: friday 13 bug? - Mailing list pgsql-hackers

Hello,

I personally ran into the exact same thing with another customer.
They are running RedHat 8.0 with (2.4.20 at the time). We had to upgrade 
them to 2.4.23 and reboot. Worked like a charm. This was about two months 
ago. I swear it was almost the exact same error.

Sincerely,

Joshua D. Drake
